Cool, Thanks so much! I think you are correct. Going back to my signal processing book, there's a requirement where carrier freq must be at least greater than the bandwidth in order to avoid overlapping of the spectra. Otherwise information of the modulating signal will permanently be lost in...
Thanks Born2bwire! It's very clear.
If hypotetically speaking, just out of curiosity, if I use a 1 MHz carrier, and modulate it just to transmit one pulse. If I try to brute-force modulate to have a mega short duration, so the frequency spreading will be huge (e.g. occupying a huge...
